Abstract

The invention discloses a display panel and a driving method thereof as well as a display device. The method comprises the following steps: using a time-sequence control circuit to output a first clock control signal into a gate drive circuit and output a second clock control signal into a source drive circuit within a frame of display time; using the gate drive circuit to load gate drive signals which are synchronized with the first clock control signal on all grid lines according to the first clock control signal; using the source drive circuit to load source drive signals which are synchronized with the second clock control signal on all data lines according to the second clock control signal. The loading time of the gate drive signals and the loading time of the source drive signals are respectively and correspondingly prolonged for the time which is the same as the delay time corresponding to a group of pixel electrodes electrically connected with all the grid lines, so that the charging time of all pixels in the display panel can be enabled to be same, and thus the display brightness uniformity of the whole display panel can be guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] Among existing display devices, organic electroluminescence display (OLED, Organic Light Emitting Diode) has the advantages of simple preparation process, low cost, high luminous efficiency and easy formation of flexible structure; liquid crystal display (LCD, Liquid Crystal Display) has It has the advantages of low power consumption, high display quality, no electromagnetic radiation and wide application range. Organic electroluminescent displays and liquid crystal displays are relatively important display devices at present. [0003] At present, both organic electroluminescent displays and liquid crystal displays generally have the problem of uneven display brightness. Taking a liquid crystal display as an example, the liquid crystal display is mainly composed of an array su...
